<p>PURPOSE:To obtain a device possible to be fitted for various kinds of dictation recording and reproducing machine systems only with changing at least a piggy back, by constituting the device with plural sound recording and reproducing parts, the first and the second circuit boards, and a freely changeable piggy back. CONSTITUTION:The titled device is constituted with one or plural sets of dictation sound recording and reproducing machines consisting of plural sound recording and reproducing parts, the first and the second circuit boards 2 and 3, and the freely changeable piggy back. As the piggy back, the first piggy back 1, or the second piggy back 15 can be used. On the first circuit board (CPU board) 2, at least, a central processing unit (CPU) 6 which controls the plural sound recording and reproducing parts based on a command from the outside, and a sound signal transmission line are loaded. Also, the second circuit board (connector board) 3 is equipped with, at least, a connector connected to the terminal equipment at the outside, and the piggy backs 1 and 15 connect the first and the second circuit boards 2 and 3 electrically. In this way, the device can be simply and easily fitted for the other systems only by changing the piggy backs 1 and 15 simply without changing other circuit part or mechanism.</p> |
